arrangements of atoms bonded together in certain combinations

Organic compound means, “All carbon-containing compounds with the primary exceptions of carbon oxides, carbides, and carbonates, which are considered inorganic”

Carbon atoms create a bond to other carbon atoms. These can form chains from two to thousands of carbon atoms in length

Carbon atoms also create bonds with hydrogen atoms if other elements such as nitrogen, oxygen, sulfur, phosphorus, and halogens

Can form complex branched-chain structures, ring structures, cagelike structures, etc.

Butane is a gas that exists at normal temperature and pressure. Butane is a highly flammable, colorless, easy-to-liquefy gas that vaporizes quickly at ambient temperature.

Cyclopentane is an alicyclic hydrocarbon having a ring of five carbon atoms connected to two hydrogen atoms above and below the plane. It appears in the form of a whitish liquid with a petrol-like odor.

Propylene is a colorless fuel gas with a distinctive odor. Although it looks and acts like propane, it possesses a double bond that gives it a combustion advantage, meaning it burns hotter. This flammable and non-toxic fuel gas is extremely combustible. Propylene is created when gasoline is refined.

Benzene is a colorless or light yellow liquid at room temperature. It is highly combustible and has a sweet odor. Benzene evaporates fast into the atmosphere. Because its vapor is heavier than air, it may settle in low-lying places. Benzene just minimally dissolves in water and floats on top of it.
